Why SJREC Is Important for Malaysia’s Sustainability Goals

The strategy for renewable energy in Malaysia is strengthening quickly. National and state policies now prioritise energy transition, carbon reduction, and responsible industrial growth. SJREC supports these frameworks by supplying large-scale renewable electricity and reinforcing Malaysia’s role within ASEAN’s long-term energy plans.

Malaysia’s Government Sustainability Policies

Malaysia has established several policy frameworks that align with SJREC’s goals:

• National Energy Transition Roadmap (NETR), which outlines renewable expansion and flagship projects
• Malaysia Renewable Energy Roadmap (MyRER), which guides long-term RE growth
• Johor Renewable Energy Policy 2030, introduced under Johor’s Green Development / Green Vision 2030 agenda, to accelerate state-level renewable capacity (including a 600 MW RE target by 2030) and support green industries
• Low Carbon Cities Framework, for municipal and corporate emissions reduction

These policies collectively strengthen Malaysia’s shift toward clean energy and create the foundation for large-scale corridors like SJREC.
